hello, my g/f works with a girl that drives an 03 ram 1500. thats all i know about the truck other than it is a gasser. her CEL was on and i checked it and got p0157 which is bank2 sensor2. can yall tell me where this would be at without knowing the engine? on autozone.com it showed the 4.7 is most common
